Mvv invention "relates to internal combus'l tion engines of the sleeve valve'type and more particularly to means yfor removing sludge from the sleeve pocketlf f l An object "of my present invention to facilitate Vthe removal: of `sludge from lthe sleeve pocket of anfinternal combustion engine by providing meansfor connecting the sleevepocket with the engine intake chamber, thereby periodically subjecting the's'aid circulated between' the `sleeve rpocket `and `the fuel mixture conducting system-carry1ng from the sleeve pocket any foreign particles, theflatter passing'to the engine combustion chamber where they are relatively harmless` to the engine'. f

F or a more detailed understanding of my invention, reference may be had to kthe ac companying drawing whichillustrates one form which my inventionmay assume,'vand in which:A H y Fig'. 1 is a verticaltransverse sectional view of a portion of a single sleeve valve internal combustion engine constructed in accordance with my invention, n Fig. 2 is a fragmentary I'vertical' sectional viewv of a modifiedy formofconstruction,

' Fig. 3 is a fragmentary verticalsectional l view of a still further modifiedlform of "construction, and f Fig. 4 is a detail sectional view taken on the line 4 4 of Fig; 3.' W1 f In the accompanying drawing, I have shown my invention incorporated with the Burt-McCollum ytype ofA sleeve `valvey engine,

in which an enginecylinder block 10 is p'rol y kof a surgeof fuel into the combustion'chamber causing anincrease 1n the vacuum presvided with one or more Cylinders 11.' {The' cylinder is closed by la: cylinder head' 12hav- 1930.' serial N o. 443,590.

ASSIGNOR"TO CONTINENTAL MOTORS OOR-ff ing a portionl depending within and spaced l sleeve pocket 14 for accommodating the upper end of, a sleeve valve 15, said sleeve valve being actuated yby any suitable mechanism (not shown) with a combinedreciprocating and oscillating movement, whereby any lpoint Aonthe sleeve traces a'closed curved path with respect r'to the cylinder Walls.' The sleeve valve isy driven at half' engine speed for the usual four stroke cycle engine. The cylinder block is provided with the kusual intakechamber or passage -16 and intake port 17 the sleeve'valve being provided with a port 18 cooperating kwith'the cylinder port toy placerthe engine combustion chamber 1.9 in communi-cation with the cylinderl 4intakechamber onthesuction stroke of the'piston 20. It will be understood that the intake chamber 16 is supplied with theusual fuel mixture yfrom the usual carburetor (not yfrom-.the cylinder Walls tofor'm an'annular shown) by way of la suitable fuel mixture f conductingmeans or intake manifold 27. n

l Difficulty has been'experienced with sleeve valve engines f by the accumulation `of, fde-` posits in the vicinity of lthe sleeve pocket,v Vthese deposits arecommonly termed sludge and are formed by carbon, water land otherV yresidualmateria'ls which` find their Way to the sleeve pocket inthe normal operationiofV `order to accomplish this Il have providedu a conduit means for connecting the sleeve pocket kwith the cylinder intake chamber or passage adjacent to the cylinder intake port.

The intake chamber is of course kfilled with'y fuelvapor under ymore or less vacuumy pressure atall times, but during the periodvwhenthe intake port is open, there is more orless l the engine. This sludge accumulation -rusts .a cylinder and an intake port'intermediate the cylinder and intake chamber, sleeve valve sures in the chamber as well as inducing a suction effect in the conduit by auto-extraction. The conduit means comprises a passage or hole 2l preferably drilled vertically in the engine cylinder block, said passage or hole opening through the top face ofthe cylinder block. A lateralpassage orhole 22 is provided for connecting the passage 2l with the sleeve pocket, said passage 22 preferably opening into the sleeve pocket adjacent the upper portion thereof.

As shown in Fig. l the upper open end of the passage 2l is closed by the flange 23 of the cylinder head which overlies the opening. In Figure 2 I'have shown a lateral iange24i carried by the cover 25, which is extended inwardly so as to `overlie the open end of the passage 21.

Figures 3 and 4c show a further modified construction in which the conduit means is formed by providing a groove 26 in the side of the cylinder wall, the groove opening into the cylinder intake chamber, but preferably stopping short of the top of the cylinder Wall, though obviously the groove could extend all the way to the top where it would be closed by the cylinder head flange. The groove 26 or hole 2l could be either cast or machined in the cylinder block.

Althoughl have illustrated but one form of my invention and have described in detail but ka single application thereof, it will be apparent to those skilled in the art to which my invention pertains that various modifications and changes may be made therein Without departing from the spirit of my invention or from the scopeof the appended claims.
